Find the value of $$[(35\div5) × \{\frac{12}{6}+\frac{25}{2} × (9-7)\}]$$​​

Correct option is D

Given:

​$$\left[ \left( \frac{35}{5} \right) \times \left\{ \frac{12}{6} + \frac{25}{2} \times (9 - 7) \right\} \right]$$ 

Concept Used:

​$$\begin{array}{|c|c|} \hline \textbf{Operation preference wise} & \textbf{Symbol} \\ \hline Brackets &[],{}, () \\ \hline Orders, of & ² (power), √ (root) , of \\ \hline Division & ÷ \\ \hline Multiplication & × \\ \hline Addition & + \\ \hline Subtraction & - \\ \hline \end{array}$$ 

Solution: 

​$$\left[ \left( \frac{35}{5} \right) \times \left\{ \frac{12}{6} + \frac{25}{2}\times (9 - 7) \right\} \right]$$ 

​$$=\left[ \left( 7 \right) \times \left\{ \frac{12}{6} + \frac{25}{2} \times (2) \right\} \right]$$ 

$$=\left[ \left( 7 \right) \times \left\{ 2 + \frac{25}{2}\times (2) \right\} \right]$$ 

​$$=\left[ ( 7 ) \times \{2 + 25\} \right]$$ 

= $$( 7 \times 27 )$$ 

= 189

Thus the solution is 189.
